IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 189,542, dated April10, 1877; application filed March 9, 1877.

To all whom it may concern:

Be it known that we, JAMES G. HALLAS and WILLIAM N. WEEDEN, both ofWaterbury, in the county of New Haven and State of Connecticut, haveinvented a new Improvement in Lamp-Burners; and we do hereby declare thefollowing, when taken in connection with the accompanying drawings andthe letters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawings constitute part of thisspecification, and represent, in-

Figure 1 a sectional side view of the burner; Fig. 2, the chimney-holderspring detached; Fig. 3, a transverse section through the wicktube.

This invention relates to an improvement in that class of lamp-burnerscommonly called keroseneburners, the object being to produce a burnerfrom very thin metal, whereby the weight of the burner will bematerially diminished.

The invention consists, first, in forming the chimney-holding springsfrom wire, with the ends turned to the right and left into substantiallythe curve of the edge of the deck, and secured by turning the edge ofthe deck inward and over the said projecting ends; also,

in the method of forming the wick and gas tube from a single piece ofmetal, whereby a passage for the gas is made outside of and separatedfrom the wick-tube, as more fully hereinafter described.

The general form of the burner does not differ materially from that ofburners heretofore constructed.

The deck or chimney-rest plate A is made from thin metal, and the edgerolled over and inward to stiffen the edge of the plate. Thechimney-springs a are made from wire, as seen in'Fig. 2, doubleddownward, the two ends 0 extending one to the right and the other to theleft, and curved to correspond substantially to the curve of the deck,and in length preferably so that the end of one spring will meet the endof the next spring,

.so that the combined extent of these ends will be substantially thecircumference of the deck. Before the deck is turned over the springsare laid in place, and then the edge of the deck turned over so as toinclose the ends 0 of the spring, and firmly hold them in theirposition. The curve, to a great extent, prevents the springs fromturning; but the coil (1 at the bottom of the springs extends beneaththe deck-plate A, as seen at the right of Fig. 1, so that a furtherbearing is made to resist the force outward against the spring. Theseinclosed ends 0 greatly strengthen the edge of the deck or chimney-rest,and thereby enable it to be made from very thin metal. The springs,however, may be otherwise applied, and a wire inclosed within the edgeof the chimney-rest to produce the same strength.

The wick-tube B (shown enlarged in Fig. 3) has combined with it thegas-tube b, making what is known as the Ambrose patent, or gas -tubeburner. The usual method of making this tube b has been to form aninde-' pendent tube, and set it in place beside the wick-tube. Adivision between the wick-tube and the passage for the gas is essential.To make these two parts from one and the same piece, a strip of metal ofsufficient width is bent into the form, starting from one edge, e, thatedge turned outward, forming a rib, f, of the interior depth of thetube; thence around until the metal comes against the rib e then turnedoutward, as at g thence parallel with the surface of the wick-tube thedistance required for the width of the gastube, when the other edge ofthe metal is turned inward, as at h, against the wick tube, thuscompleting in one piece the wick-tube and the gas-tube, with the passageto the gastube entirely separated from the wick-tube.

We claim- 1. In a lamp-burner, substantially such as described, the deckor chimney rest, constructed with its edge turned inward, and inclosinga wire to form the edge of the chimney-rest, substantially as described.

2. In a lamp-burner, substantially such as described, thechimney-holding springs formed piece of metal, with a division betweenthe from wire, the ends of the said springs turned wick and gas tube,substantially as described.

into a horizontal plane with the chimney-rest, and secured thereto byturning the edge of the chimney-rest over the said ends, substantiallyas described.

3. In a lamp-burner, the combined wick and gas tube, formed complete ina single JAMES G. HALLAS. WM. N. WEEDEN. Witnesses:
